To all whom it may concern:

Be it known that I, ALBERT E. ROBERTS, a citizen of the United States,residing at Norwalk, in the count-y of Huron and State of Ohio, haveinvented a certain new and useful Improvement in Rubber Overshoes, ofwhich the following is a full, clear, and exact description. V q

The prior Patent No. 736,156, granted to sandal overshoe or rubber, ofwhichthe front part of the upper is provided with an :internal bead,wherein a cord is embedded.

This cord, embedded in this internal bead, extends around the toe andalong the .sides of the upper near the top edge thereof to a point nearthe heel; and it goes around the [heel embedded in an external bead. Thepurpose of the internal bead'in the front part of the upper is to gointo the crease between the upper and sole of the shoe on which therubber is used, so that fit overthe rubber is made diificult. Therubberwhich forms the subject matter of said patent is being manufactured andsold under the name of Eversticl Whensuch a rubber is nicely fitted tothe shoe upon which itis worn, it is entirely "satisfactory. If,

however, an Everstick rubber is put onto a shoe having a solemuchthicker than that of the shoe for which therubberwas-constructed,the said bead cannotoverhang the shoe sole, and therefore the rubber isnot held on the shoe. If, on the other hand, such a rubber is put ontoashoe havinga sole much thinner than that for which the rubber wasintended the said internal bead will not enter the crease of the shoeand will not engage with the sole thereof. It will, on the contrary,engage with the upper some distance above the crease, andthe result willbe that the rubber will not fit the shoe properly andwill have more orless play thereon. It is therefore likely to come off easily; but thechief objection is that as the rubber moves onthe shoe this bead. willchafe the leather of the shoe upper. This sometimes does no greaterdamage than to wear away the pol- 'ish, but frequently it wears. intothe leather itself. For the reason stated, therefore, the Everstiokrubber is not satisfactory unless it is worn upon a shoe to which it isfitted with more or less exactness. It is therefore necessary for themanufacturers of the heel part of the rubber.

provide a sandal rubber having all of the desirable qualities of theEverstick rubber, but which doesnot have to be so nicely fitted to theshoe on which it is worn; to provide, in other words, a rubber whichwill be adaptable to shoes differing very greatly in the thickness oftheir soles.

The invention consists of a sandal rubber having, near the upper edge ofthe low front part' of the upper, an external bead which is extendedback to the heel portion of the upper,- in which bead a non-stretchablewire or cord. is embedded, said rubber having a high heeled portion, anda strap of variable length adapted to go over the instep of the shoe onwhich the rubber is worn. V

The invention, as illustrated in the accompanyingdrawing is hereinafterdescribed, and the invention is definitely defined by the appendedclaims.

In the drawing Figure l is a side elevation of an overshoe in which thepresent invention is embodied. Fig. 2 is a sectional view showing therubber, the shoe therein, said section being in the plane indicated byline 22' on Fig. 1; and Fig-l 3 is a section on line 33 on Fig. l.

The low. front part A of the upper of the rubber has an external bead aarranged at a suitabledistance, as shown, above the sole of the rubber,said bead extending around the toe and then back on both sides of the Inthis external bead a cord or wire B is embedded, which; cord or wireshould be of substantially nonstretchable material. This bead is placedat such distance above the sole C of the rubber that, when the rubber isapplied; to a shoe, this bead will be above the crease of the shoe andwill engage with that part of the shoe upper ;which is inclining awayfrom the adj acentedge of the sole. Those familiar with this art willunder-' stand that in making the described rubber it is to be made upona last, the toe part of which curves upward approximately, as shown bydotted lines in Fig. 1. If, when so curved up at the toe, the upper ofthe rubber stands at approximately right angles to the sole thereof, thelast may be easily removed. hen, thereafter, the rubber is bent down atthe toe, as it is when in use, the upper A will incline inwardly so asto overhang the part of the upper just above the sole as shown.

The heel part D of the rubber will at its upper edge be inclined forwardso as to fit the heel of the shoe.

E represents a strap which is a part of the upper of the rubber and isarranged so as to go over the instep of the shoe. This strap must be ofvariable length. As shown this result is attained by making the strapelastic.

. When this rubber is on a shoe, the strap prevents the heel part of therubber from coming off, and the cord prevents the low front part of theupper from assuming any position except the inwardly inclined positionshown and above referred to; and therefore the front part of the upperis held on.

In order to give a suitable anchorage to the strap E, and to prevent thestrap from distorting the rubber, a fabric strip G is placed between theouter rubber layer and the lining H, being vulcanized to the former,this fabric strip lying in the shankpart of the upper and of the sole;-that is to say, it is fixed to the sole as well as to the upper. Thestrap E is practically a continuation of the rubber layer of the upper,and the upper ends .of the strip Gr extend into that part of the strapon both sides of the overshoe, when it extends from the upper.

Having described my invention, 1 claim:

1. A sandal rubber, the upper part of which is low in front and high atthe heel, combined with a cord applied externally and extending alongthe sides and around the toe of the low front part of said rubber,thereby leaving the inside of the low front part smooth, and said rubberhaving an elastic strap which is adapted to go over the instep;

2. A sandal rubber, the upper of which is low in front and high at theheel and which has a strap of variable length adapted to go over theinstep of the shoe to which the rubber is applied,the low front part ofsaid upper having an external bead extending around the toe and alongboth sides thereof to points near the heel, said bead leaving theinterior of the rubber smooth and being at such distance above the soleof the rubber that it will be well above the crease of the shoe on whichthe rubber is adapted to be worn,-there being a cord embedded in saidexternal bead and being substantially coextensive therewith as tolength.

3. A sandal overshoe having a sole and an upper high at the heel and lowat the sides and toe, said upper comprising an outer layer of rubber andan inner fabric lining, an elastic strap adapted to pass over the instepof an inserted shoe and joining the outer rubber layer at each side ofthe upper, and a fabric strip arranged beneath the lining and united tothe sole, to the upper, and to the end portions of the strap.

In testimony whereof, I hereunto my signature in the presence of twowitnesses.
